Changing queue depth

I've been observing the performance monitor on a two node VSA cluster. We have several DELL servers with MD1120s and MD1000s attached to Perc6e controllers. Each vsa node is backed by a RAID 50 of 16 146GB 10k SAS disks. My observations lead to the fol1owing question:

A) The queue depth fluctuates but never exceeds 32. Is the queue depth for the VSA capped at 32 and can it be changed?

Re: Changing queue depth

The queue depth is not capped by the VSA. The initiator you are using, or OS, might be what is capping it actually. ESX might be capping that, I think you can edit it but I'm not sure, never needed to before.

Re: Changing queue depth

Thanks for your response. I've been trying to determine the source of my poor iscsi experience. I thought this was maybe due to the queue depth but further experiments seem to point more to a network limit.I started another thread with this specific issue, hopefully you can assist.
